The LAPD has reportedly opened a criminal investigation into Rob Kardashian after he was accused of physically threatening Pilot Jones, the R&B singer seen kissing his fiancée Blac Chyna in photos that were leaked this week. A police report on Kardashian was filed in North Hollywood, and LAPD's Threat Management division is investigating the case, according to

TMZ. Blac Chyna, who was linked to Jones before she began dating Kardashian and became pregnant, was rumored to have rekindled her romance with Jones during one of her numerous breaks from Rob earlier this year. TMZ reports Kardashian sent Jones several threatening text messages, including one that said, "Leave my wife alone. I'm not playing with you."
